SMD Bluetooth Module HC 05 4 Pin Master Slave

The HC-05 Bluetooth Module is a highly reliable and easy-to-use wireless communication solution designed for transparent serial connection setup. This module operates on Bluetooth Specification v2.0+EDR, providing stable communication at 2.4GHz ISM band with GFSK modulation. What makes the HC-05 special is its dual-mode capability, allowing it to function as either a master or slave device, making it incredibly versatile for various applications. With an operating range of up to 10 meters and data transfer speeds of up to 2.1Mbps, it's perfect for IoT projects, Arduino applications, wireless data logging, and remote control systems. The module features a simple 4-pin interface (VCC, GND, TXD, RXD) and operates on 3.6-6V with low power consumption of just 50mA. Its default baud rate of 9600 makes it immediately compatible with most microcontrollers. Whether you're building a home automation system, wireless sensor network, or robotic control interface, the HC-05 offers a cost-effective and reliable solution for adding Bluetooth connectivity to your projects.
